DUPLEX ECCENTRlC-VALVE FOR HEATERS, 800.

SPECIFICATION forming part of Letters Patent No. 453,109, dated May 26, 1891.

Serial No. 379,688- (No model.)

To all whom it may concern:

Be it known that I, JACOB DRnIsoRNnn, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Duplex Eccentric-Valves for Heaters, &c., of which the followin g is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a duplex eccentric-valve for heaters, &c., that has an eccentrio-Valve stock with duplex ports in the stock and an eccentric-packing in the case and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a side view of the valve-plug seated in its tubular case, with details of the hot-water or steam pipe in registered connectiontherewith. Fig.1lisalongitudinalvertical section taken on line II II, Fig. IV, and shows the eccentric-valve plug in its case and the said case provided with an eccentric-packing that closes the parts of the valve when said eccentric-valve registers with said eccentricpacking. Fig. III is a side view of the plug and shows its eccentric-valve. Fig. IV is a vertical section taken on line IV V, Fig. II, and shows the eccentric-valve of the plug in registry with the eccentric-packing of the case and consequently with the Valve-ports closed. Fig. V is a like View taken on the same line with the eccentrics out of registry and the valve in consequence at open port; and Fig. VI is a vertical section taken on line VI VI, Fig. II, through the plug, the case being in elevation,and shows the plug-valve in its case at open port, reversed from its position in Fig. 11. It also shows one of the packing-rings, which packing-rings secure steamtight joints at each end of the valve system.

Referring to the drawings, 1 represents the tubular metal case, and 2 is the sexangular projecting wrench-seat at one end of said case, by which it is turned to respectively open and close the valve-ports.

3 represents the eccentric-packing, of brass, or any other suitable metal, that is inserted and projects internally on one side of the tubular case, and a are annular integral projecting collars within said tube, which form the end joint-seats of said case, against which the packing-rings 5, which may be of brass or any other suit-able material, are compressed to make steam-tight joints.

6 represents the Valve-plug coupling-joint pipe that connects the respective receiving and submitting joint-pipes 7 of the hot-water or steam-pipe systems. The peripherallyscrew-threaded joint ends 8 of said pipes engage in their internally-screw-threaded socket-seats 9 in the ends of said valve-plug, so as to effect steam-tight joints at their coupling.

10 represents the eccentric-valve that has a projecting periphery on one side of the valve-plug to provide said eccentric, which, when by the rotation of the case the eccentricrpacking 3 of said case registers with said eccentric-valve 10, the ports 11 of the duplex coadj utary angle valve-tubes 12 are closed, as shown in Figs. II and IV; but when the case is again turned, so as to bring the two eccentric members respectively in the plug and casing out of registry, then the ports are again opened, so as to provide afree current of hot water or steam, as the case may be, from the one port 11 into the intercommunicatory hot- Water or steam chamber 13, as shown in Figs. V and VI.

14 represents an annular peripheral swellcollar near the outer end of the valve-plug, between which peripheral collar let of the valve-plug and the internal collar 4 of the case one of the packing-rings 5 is closely nipped, so as to effect a steam-tight joint between the hot-water or steam chamber 13 and said peripheral collar of the plug.

15 represents the scxangular wrench-seat of the valve-plug, by which it is turned into its screw-coupling connection with the pipe 7 at the outer end of said plug, and if the screwsocket 9 of the plug and the peripheral screws 8 of the pipe-sections 7 are respectively at their reverse ends tapped right and left handed, then the one rotary movement of the valve-plug will simultaneously couple both ends, otherwise the junction of the j oint-pipe 7 at the inner end of the valve-plug may be subsequently effected by the usual grip-ton gs or wrench around said pipe-section.

16 represents the internally-screW-tapped perforated flange-collar, in the center perforation 17 of which one of the joint-pipes 7 is seated, and 18 are socket-wrench seat-holes in the face of said collar, in which the clutch pins of the wrench are seated to maintain its hold while it turns said screw-tapped collar onto the steam-tight engagement of its peripheral screw-seat 19 around the inner end of the valve-plug. WVhen said collar is screwed home, its inner end'tightly nips the packingring 5, that is located at that end of the joint, compressing it against the annular shoulder 4 of the casing at said end, and which packing-ring shuts off the exit of steam around the end and periphery of said collar, where it (the collar) rests in its countersunk seat 20 within the wrench-seat end 2 of the case 1.

21 represents a peripheral screw-terminal to the valve-plug for use as a screw-tight attachment for the screw-threaded dischargeorifice of ammonia and other tanks when the invention is used as a draw-valve from any tank or reservoir to which it may be attached.

I have described the valve-plug as stationary and the case as rotary, because when attached as a valve-coupling section to hot-water or steam pipes, or as a draw-valve to ammonia and other tanks and reservoirs, it is generally most convenient to have said valveplug stationary and the case rotary; but I do not confine myself to said respective arrangeand maybe dispensed with,in which case the screw-socket 9, in which the screw-terminal of the pipe-section 7 is jointed, will be located ahead in the main body of the plug, as shown in broken lines in Fig. II. The central ports 22 of the tube-channels 12 coiucidentlyregister with the junction-ports 23 of the tube-centers 24 of the pipes 7.

The attachment-screw 21, which has been described as an integral extension of the valveplug 6, may, as shown in the broken lines in Fig. II, be of disintegral construction when it has a rear extension 25, that engages in the internally-screw-threaded socket-seat 9 in the initial end of the valve-plug.

I claim as my invention 1. The combination of the eccentric-valve plug 10, the tube-case that houses said valveplug, having a seat or socket in one side and the solid eccentric-packing inserted in said socket, the said eccentric-valve and packing arranged to register together in closed port and separate in open port, substantially as and for the purpose set forth.

2.
